The Spotted Longhorn Beetle (Rutpela maculata) can easily be confused with the Four-banded Longhorn Beetle (Leptura quadrifasciata).
The difference between the two is that Rutpela maculata has black-yellow ringed antennae and Leptura quadrifasciata has all black antennae (with the female having light brown antennae tips).
